Better solution for us V8 guys looking to eliminate the Torque arm that is not supposed to be there. Pm me if you are intrested....

Interested...Bump!

 

Outstanding. Can't wiat ;o)

 

Man that's a great mod Paul. I am glad I sent you my rear subframe.

 

Thanks guys, I should have some updates this coming week.

 

Paul,

The guys sticking with the rotary could benfit from this too. They would just need to add a trans brace and ditch the power plant frame I would think? I think Aspec offers a trans brace.

Rotary guys break Power Plant frames all the time due to the twisting effect at the mounting point at the diff. I broke mine when I was rotary and I was making 430RWHP and 380some RWTQ

 

I would post this in the 3rd gen section too.

 

A pair of urethane or Nylon differential bushings would prevent that quicker, much cheaper, and with far less labor than completely disassembling the rear of the car to send the subframe to someone for modification.

Paul, to be honest, beyond eliminating the need to use Hinson's (potentially) poorly welded torque arm, I don't see any benefit whatseover to your mod. You're still stuck with the same weak cast iron differential housing, the same lack of differential choices, and the same lack of gear ratios you had before. For $1,000 + shipping both ways, you're not even increasing the strength of the axles. You're just mounting the differential differently.

Am I the only one who gets this?

 

Jim, do you have proof that with the diff mounted this way that it is weak? In all honesty I haven't heard that the Cobra diff was bullet proof either. My solution doesn't strengthen the diff (which I never claimed) it just eliminates the diff being twisted by the torque arm or the PPF.
My mod helps those who choose to retain the stock diff beacuse they might have already purchased a Kazz LSD and a pair of 300m axles (which are proven too support 600+rwhp). As for gear choices, I am happy with the 4.10 gears I have and many have said they are more then happy with the 3.90 gear set that is available.

Jim, I would not like to get into a pissing battle with you over this so lets just say like I posted on swaptech that I am not going to make a list of reasons for anyone to purchase this but just let people decide for themselves. I never post any ill comments in any of your threads so please don't start here.

Thank you,

Paul

 

Of course it's not, but the majority of breakage is due to Ford's mounting solution, which puts a lot of stress on the rear of the case, and the double-bushing mounting of the rear suspension and subframe which make the Cobra extremely susceptible to wheel hop. None of those problems apply to my system of mounting it in the FD and it is far stronger than the Mazda unit it replaces.

I didn't say you claimed that it strengthened the differential. I pointed out that it does not strengthen the differential.

The differential will still try to twist even without a torque arm or PPF. It's a natural result of the differential trying to turn with the driveshaft and the pinion gear trying to walk up out of the teeth of the ring gear instead of turning it.

Fine, but it's still a lot of cash and effort just to eliminate needing a torque arm or PPF.

I don't look at it as an ill comment, but merely pointing out details that don't seem to have been discussed.

If your modification can't stand up to scrutiny, then you probably shouldn't be advertising here. The fact is, you can't argue with my points and while people are obviously able to decide for themselves how to spend their money, they should be aware of what they're getting into. I can't understand why you'd object to that, unless you were just trying to make a buck at their expense.

 

Jim, when you speak, it seems like everyone get's touchy (defensive). LOL

 

Jim always chimes in with his negative comments. Go finish your own 5 plus year project. You are just an *** as far as I am concerned, and probably 90% of the rest of the Forum members.

You do this **** on this forum and several others.

 

Jim, all good points and like I said before I am not afraid of anybody's point of view, let people decide for themselves.
I also said before I am not in buisness making products like this for a living, just offering this mod to those who asked me to make it for them which is how this group buy started in the first place.

Jim, the differential will still expereince the natural twisting motion that you explained but what it will not experience is the extra twisting created from the torque the motor transfered through the PPF or Torque arm. Also I have not had a Tranny mount failure related to the use of the Torque arm which many have experienced. I did not weld up my spot welded tunnel mounts, they are currently as they were from the factory.

BTW Jim, have you done any real world testing to back up some of your book smarts? From all my reading there is only one car that actually moves under it's own power using your Cobra rear end swap, and Hyperion has modified your subframe in a few ways so not really sure if that counts. By the end of this I will have 10 subframes out there including mine which I am sure more then 1 will be in use for some real feedback from on road testing. I have tracked my car on 2 ocassions and beat the **** out of it on the street many times, so far so good! Can you say the same???? NO! Your car doesn't move unless you push it!

As for making money at others expense, that's a good one. I am supplying a product and a service which I am charging for, am I making money? Yes, as much as you might think? NO, I don't have the connections to fab things up like you for such a good price. I am a Machinist with more then 12 years of practice, never claimed to be a pro fabricator, but I am sure if it came down to it I could easily do this project myself. As of right now I don't have the time so I have some help.

 

Oh, ouch. That hurt.

You should really learn to count. Maybe that's why you're charging $1,000 for something that should cost about $450-500 with materials, labor, and a reasonable profit margin?

Oh, ouch. That hurt.

Well, at least that's the truth.

Good luck on your group buy Paul. Just to be an ***, I've reported your thread because I doubt you got permission to advertise it on this forum beforehand.

 

Well done Jim! I don't need to advertise, as my group buy is currently CLOSED!!!

BTW- if you can do it for $450-500 copy it and sell it, I don't really care! Spend some more time in your garage and get your project done.

 

I know everyone gets up in a tiff when Jim notices issues with things, but he is correct in the first post. The whole idea of this is just to get rid of the torque arm (or PPF if you're dorito powered), correct?

That's the only benefit of this design, to get rid of the torque arm and mount the differential under its own merits in the rear, right?

My time under an FD is minimal, and the car I helped put together hasn't had any failures yet (although it was a Granny's setup, not a Hinson "whoops forgot to weld that" setup), but it does seem that there would be simpler ways to accomplish this. That said, at least Paul has made this an available option for people wanting to go this route.

 

Jim's just a douche. That's all I am going to say. He's probably sore because he did not think of it first. I am done. Now jim can go ahead with his typical b.s. and write a book on how much of a tool I am.

 

What a little hurt my feelings cry baby. I'm telling on you. Waaa waaa waaa waaa waaa. Proves my point, he's sore. Paul's mod will cut into all those Cobra IRS orders.

 

I don't think Jim still makes the Cobra subframes (actually he never did, he just provided them), but if he did, do you really think that has any effect on his finances at all?

Much like Paul, that was done to help the community. Much like Paul, he did it for himself and was generous enough to provide it to the community.

I can see people getting pissed at Jim for his, creative, use of tact , but I can say 100% that I have never ever seen Jim say anything that was contrary to the benefit of the community. Better put, regardless of personal bias or opinion, I've never seen Jim put down something for his own sake, that was a benefit to the community.
